3 Claims. l

The principal object of the invention is the provision of a machine which reduces the time required in preparing wall paper for application. Another object is the provision ofA a machine which provides means uniformly spreading paste on Wall paper with means located thereon for uniformly trimming the paper simultaneously.

with the application of the paste thereto.

Further objects and advantages of the invention will be apparent in the course of the following description, and that which is new will be pointed out in the appended claims.

The most satisfactory manner of carrying out the principles of the invention in a practical and eicient manner is shown in the accompanying three sheets of drawings, in which:

Like characters designate like parts throughout the several views.

In order that the advantages of the invention may be more fully understood, I will now take up a detailed description thereof in which the same will be more fully described.

Referring now to the drawings in detail, A indicates a table or other support for the machine, and B designates the wall paper.

The machine is provided with a base comprising an angle member i which extends along each side and across the rear portion of the machine, and which is adapted to provide a support for the machine on a table or other surface A. A U-shaped uprightly-disposed frame 2 is rigidly secured to the side frame members i near the rear portions thereof with the same extending across from one side to the other oi the machine.

A cutter bar member 3 is provided with a supporting frame t located at and rigidly secured to the forward ends of the frame member' l. The supporting frame (i extends upwardly from the base frame i and extends across the forward end of the machine. A hinge 5 is provided at one end of the cutter bar 3, with the opposite end thereof being removably secured to its support 4 by means of the bolt E, the purpose of the hinge' 5 and bolt 6 being further set forth hereinafter.

Each side of the machine is provided with a bar member 'i which has its forward end rigidly secured to theV cutter bar supporting frame li, as more clearly shown in Figures 1, 2, 4, 8, and Q. The bar members l are further rigidly secured ,to the respective upwardly extending legs oi frame 2, also as shown in Figures 1, 5 12, and 13. The rear end of each of the members 'l is provided with an angularly-disposed slot 8, the purpose of which will be more fully hereinafter set forth.

A rod member 9 is located near the forward end of the machine and is removably journalled at each end thereof in a slot i0 formed in a: respective bar member l, and is adapted to support a roll of wall paper, as shown in Figure 1.

A paste pan or receptacle i! is pivotaly sup ported between the side upright members 2 by means of pins i2, with the same being journalled in slots i3 which are formed in the members 2, and with the pins l2 being rigidly secured through respective ends of the pan Il.

A paste roller' Hl is rotatably supported within `the paste pan li by means of a pin i5 concentrically located in each end of the roller. The pins are removably journalled in respective slotted brackets I5 which are secured within the ends of the paste pai-1 il, as more clearly shown in Figures 5, 6, and 13. A channelled groove I7 3 is formed around the roller near one end thereof, the purpose of which will be hereinafter set forth.

A Contact roller I8 is positioned above paste roller I4 with the shaft I9 thereof being journalled in slots 20 of the vertical frame members 2, as shown in Figures 1, 12, and 13. Each end of the shaft i9 is provided with a channelled groove for the reception of the upper end portion of a respective tension spring 2l, with the lower ends of the tension springs being secured through a fastening 22. The springs 2l provide means holding the contact roller against the paste roller I4, and also provide means holding the wall paper B in contact with the paste roller while being passed through the machine. A circular knife 23 is secured to one end of roller IS and is adapted to extend into the channelled groove Il of the paste roller I4, and provides means for trimming one edge of the wall paper as the same passes between rollers Ill and IS.

An auxiliary roller 2Q is located at the rear portion of the machine, and has a pin 25 in each end thereof which is journalled in a respective slot 8 of the bar member l. A collar 26 is located at one end of roller 24 and provides means for guiding the length of wall paper as the same passes thereover. It will be noted, by reference to Figures 3 and 4, that the guide collar 26 is positioned in alignment with the knife member 23 of the contact roller IS.

In order to provide means for adjusting the position of the roll of wall paper laterally within the machine, I have provided an adjustable guide bar 27 at each side of the machine, with the same being located within the machine with respect to the side bar members l, as more clearly indicated in Figures 2, 4, 8, and 9. Each of the guide bars has a pair of brackets 28 secured thereto and into which inner end portions of adjusting screws 29 are revolvably secured. The screws 29 are threaded through the bars 'l and the bosses 3D, and have slots formed in the outer ends thereof for adjusting purposes.

A pan adjusting rod 3l is adjustably positioned and suspended from the bars l, and is located be-` tween the pasting roller Id and the auxiliary roller 24, as shown in Figures l, 3, 4, 5, and 12. The adjusting rod is adapted to engage lug members 32 which are secured to the rear side of pan II.

A stop bar member 33 is secured to the rear frame member I by means of rivets or by other suitable means 3A. It will be noted, from Figures 3, 10, and 11 that the rivets extend through elongated apertures formed in the bar 33 which permits vertical movement of the bar with relation to the frame member. In use, the machine is usually placed at one end of a table or other support A with the bar 33 extending below the lower edge of the frame member I, as shown in Figure 1 and 10, and preventing movement of the machine forwardly as the wall paper is taken therefrom. Figure II shows the position assumed by the stop bar when the machine is placed on a flat surface and not adjacent an edge thereof.

Operation In the operation of the machine, the pan II is filled to the proper level with paste of the proper consistency. Rod 9 is removed from the machine and inserted longitudinally through a conventional roll of wall paper. The paper is threaded between the paste roll I4 and the Contact roll I8, after which the guide bars 2 are adjusted to their proper positions with relation to the roll of paper to align the same laterally of the machine with relation to the knife member 23. The paper is then passed around the auxiliary roller 24 as shown in Figure l, and then brought forwardly over the contact roller I8 and between the frame and the cutter bar 3.

As the wall paper is pulled from the machine, the paper, passing between the paste roller and the contact roller, causes these rollers to revolve in the direction indicated by the arrow-s in Figure 1. As the paper passes over paste roller I4, the paste s transferred from the roller to the under side of the paper. Also, as the paper passes between the contact roller and the paste roller, one edge thereof is trimmed by the knife 23.

When the desired length of paper has been pulled from the machine, the paper is torn off in the usual manner by an upward motion against the cutter bar.

The rear edge of the paste pan II forms a scraping means determining the amount of paste adhering to the paper and is adjustable with rela tion to the paste side of the wall paper as the same travels from the paste roller Ill to the auxiliary roller 2Q by means of the adjusting rod 3l. The adjustment of the rear edge of the paste pan II with relation to the paper provides means governing the amount of paste carried by the paper. If a heavier coating of paste is desired, the rear edge of the pan is lowered with relation to the paper passing thereover. If a thinner coating of paste is desired, the rear edge of the pan is adjusted upwardly by means of rod 3I, into tighter contact with the under side of the paper, with the excess paste being returned into the pan.

When it is desired to clean the machine, the tension springs 2i are removed from the ends of shaft I9, permitting the contact roller I8 to be lifted upwardly and forwardly out of the slots 2U. rIhe paste roller I4 :can then be removed from its position within the pan II by merely lifting the same upwardly, after which the pan II can be removed by an upward and forward movement. It will be further noted also that, due to the paste roller Ill being journalled within the paste pan II, the roller may be removed with the pan. Auxiliary roller 24 is also removable from the machine by an upward and rearward movement. The cutter ba'r 3 can be readily accessible for cleaning by removal of bolt 6 which will permit the bar to be swung upwardly by means of the hinge 5. It will be noted that a catch of the eccentric type may be satisfactorily substituted for bolt 6 which will permit of faster action in releasing the one end of the `cutter bar 3 for hinged movement.

I desire that it be understood that I am not to be limited to the exact form and arrangements of the parts herein shown and described.

I further desire that it be understood that changes and additions may be provided in the machine for the provision of paper of different widths, insofar as the changes may fall within the scope of the appended claims.

Having now fully shown and described the invention, what I claim, and desire to secure by Letters Patent of the United States, is:
